Description
A security vulnerability has been detected in vgmstream up to r2117. Impacted is the function add_entry of the file src/meta/txtp_parser.c of the component txtp. Such manipulation of the argument range_start/range_end leads to resource consumption. The attack may be performed from remote. The exploit has been disclosed publicly and may be used. The name of the patch is 4b6a02dd1aff6428255db912563d77d4cb0a143e. It is advisable to implement a patch to correct this issue.
A vulnerability exists in vgmstream versions through r2117 within the TXTP parser. The issue arises in the 'add_entry' function of 'txtp_parser.c', where improper handling of the 'range_start' and 'range_end' parameters allows for unbounded expansion of subsong entries. This flaw can be exploited remotely, causing excessive memory allocation and CPU usage, ultimately terminating or stalling the application. The vulnerability has been publicly disclosed and is present in the main branch commit 'c01f584b97c5f4567f49022872ba967ebf03917d'.
The vulnerability has been fixed in the vgmstream repository. Users should update to the latest version.
